Operator ruling (Andre, 2026-07-21): the STOP was correct and the diagnosis
right — §7 items 1-2 did not fail because the instrument is broken, but because
they were worded under the naive-funnel prior. Under the ratified posterior the
pool is a MIX (shared bridge → shared exit_signature → larger anonymity set →
higher H). Corrected pre-freeze, logged transparently (no HARKing).
- rq2p3-mechanism-prereg.md §7: item 1 re-anchored on the FROZEN bridge-federated
branch (injective fresh-bridge → m_i=1 → H≈0, constant c=1/C — a pool draws with
replacement so it cannot reproduce the zero-variance degeneracy); item 2 B=1 →
c=1.0 AND high H (maximal mix, "low H" refuted by construction); added a §7 scope
note (the gate validates the INSTRUMENT and must NOT pre-assert the H-vs-c sign —
that stays the two-sided confirmatory question H1/H2). Confirmatory hypotheses
unchanged.
- docs/stage-05-rq2p3-gate-clarification.md: dated deviation-rationale log (cites
the dry-pass output, no number invented; records the two-sided direction-agnostic
pre-commitment is untouched; the mix ρ 0→+0.838 is an exploratory finding that
strengthens note-unique-bridge-artifact.md).
- rq2p3_calibration.py: item-1 teeth moved to frozen_branch_regression() on the
untouched bridge-federated branch; item-2 now asserts c=1.0 AND high H; added
all_pass aggregate. confirm.py/stats.py/confirm_load_rq2.py untouched.
Re-run: all four gate items PASS with real teeth (all_pass=True). Synthetic/DRY
only, no confirmatory record read. FREEZE STAYS A HUMAN GATE: §10 empty, no
confirmatory RQ2-P3 cell until operator records the SHA-256 + signs off. Lead
prereg SHA f22331a72e... untouched; worktree-only.

Build the funnelling-mechanism instrument for the RQ2-P3 follow-up: a new
`bridge-federated-pool` topology drawing each circuit's bridge from a finite
willing-bridge pool (size B) under Zipf willingness skew (alpha), so bridge
concentration genuinely varies as a manipulated IV. Defensive measurement only:
synthetic seeds, no engine, no traffic, no confirmatory record read.
- assembler.py: add `bridge-federated-pool` branch + zipf_weights/weighted_draw
helpers; existing lead `bridge-federated` branch left untouched and
bit-reproducible (fresh bridge per seed).
- battery.py: enumerate_rq2p3_cells() = B{2,4,8} x alpha{0,1,2} + anchor B=50,
alpha=0 (separate fn; frozen 6-cell lead lattice unmutated).
- analysis/rq2p3_calibration.py: DRY synthetic-only §7 calibration gate; no
confirmatory data read. confirm_load_rq2.py/confirm.py/stats.py unchanged.
- tests/test_sor_rq2p3_pool.py: 9 synthetic tests (helpers + pool reuse/variance
+ lead branch reproducibility).
Calibration gate RAN: items 3 (monotonicity) & 4 (entropy) PASS; items 1 & 2 do
NOT match their naive-funnel wording because the ratified posterior yields a MIX
(rho>0 across the whole sweep incl anchor rho=+0.838; B=1 -> H=2.54 bits HIGH) --
the note-unique-bridge-artifact.md prediction, surfaced early. HARD HOLD: no
confirmatory battery, no prereg freeze; NEEDS-OPERATOR banner raised for the §7
item-1/2 re-word decision. Lead prereg SHA f22331a72e... untouched; worktree-only.
